¶ Introduction
The goal of this guide is to achieve a complete monitoring of your Linky energy meter with a Raspberry, a teleinfo module and the information plugs of your energy meter.
Here, we have a Raspberry Pi 2 model B, however it will work on any Linux or BSD with some tuning.
This should work on any european energy meter with L1/L2 plugs, not only the Linky.
¶ Hardware needed
You must have:
- A raspberry with a good SD card
- A serial module, I use this: https://www.tindie.com/products/hallard/micro-teleinfo-v20/
- Two copper cables (I use 1,5mm2)
At the end, you will have this kind of Grafana Dashboard:
¶ Connecting the system
You need to set up the system like this (you can invert L1 and L2, it doesn't matter):
¶ Configuring the system
¶ Configuring InfluxDB
Configure the InfluxDB repository:
curl https://repos.influxdata.com/influxdb.key | gpg --dearmor | sudo tee /usr/share/keyrings/influxdb-archive-keyring.gpg
echo "deb https://repos.influxdata.com/debian $(lsb_release -cs) stable" > /etc/apt/sources.list.d/influxdb.list
Install the database:
apt update && apt install influxdb
Enable the service and start InfluxDB:
systemctl enable influxdb && systemctl start influxdb
¶ Configuring Grafana
Configure the Grafana repository:
wget -q -O - https://packages.grafana.com/gpg.key | sudo apt-key add -
echo "deb https://packages.grafana.com/oss/deb stable main" > /etc/apt/sources.list.d/grafana.list
Install Grafana:
apt update && apt install grafana
Enable and start Grafana:
systemctl enable grafana-server && systemctl start grafana-server
¶ Installing the Python script to retrieve the data
Test your serial connection with this command (You can exit with CTRL+A followed by CTRL+Q):
picocom -b 1200 -d 7 -p e -f n /dev/ttyUSB0
You should have something like this:
root@enedis-pi:~# picocom -b 1200 -d 7 -p e -f n /dev/ttyUSB0
picocom v3.1
port is : /dev/ttyUSB0
flowcontrol : none
baudrate is : 1200
parity is : even
databits are : 7
stopbits are : 1
escape is : C-a
local echo is : no
noinit is : no
noreset is : no
hangup is : no
nolock is : no
send_cmd is : sz -vv
receive_cmd is : rz -vv -E
imap is :

logfile is : none
initstring : none
exit_after is : not set
exit is : no

Thanks for using picocom
Install the prerequisites:
apt install python3-pip
pip3 install pySerial influxdb
Or on the latest Debian 13:
apt installpython3-serial python3-influxdb
Download and launch the script to test it:
wget https://raw.githubusercontent.com/stylersnico/teleinfo-linky-with-raspberry/master/teleinfo.py
python3 teleinfo.py
If you don't experience any error in 5 minutes, exit with CTRL+C.
¶ Checking the data
Launch Influx to check if the data has been created:
influx
Connect to teleinfo and show the series:
USE teleinfo
SHOW SERIES;
You should have something like this:
Connected to http://localhost:8086 version 1.8.10
InfluxDB shell version: 1.8.10
> USE teleinfo
Using database teleinfo
> SHOW SERIES;

¶ Creating the service
Create the following service:
nano /etc/systemd/system/teleinfo.service
Fill the file like this:
[Unit]
Description = Run teleinfo python script
After = network.target
[Service]
Type = simple
ExecStart = python /root/teleinfo.py
User = root
Group = root
Restart = on-failure
SyslogIdentifier = teleinfo
RestartSec = 5
TimeoutStartSec = infinity
[Install]
WantedBy = multi-user.target
Now, enable and launch the service:
systemctl daemon-reload
systemctl enable teleinfo.service && systemctl start teleinfo.service
¶ Configuring the display
¶ Configuring InfluxDB source in Grafana
Open Grafana from the following URL:
http://IP_RASPBERRY:3000
Go to Configuration -> Datasources -> Add a InfluxDB datasource.
Configure it like this:
¶ Importing Grafana dashboard
Download the .JSON file from github: https://github.com/stylersnico/teleinfo-linky-with-raspberry/blob/master/grafana_dashboard_teleinfo.json
Now, import the file in Grafana:
You should have the dashboard like the one you see at the beginning 
Don't forget to adapt the price calculation to your bills on the dash.
